I have notice vision differences due to tears as long as I can remember. Halos and moving objects with glistening lines. People with brain injuries often process visual images differently. Our brains do not ignore the many distractions as well as healthy brains do. It can be very annoying. We have to learn to not get too focused on these annoyances.

As a younger person, I would blink to see what images would manifest and try to see it there was a pattern or if I could manipulate the image. At about 40 yo, I complained about them to an optometrist and was referred to an ophtho to get checked. They were explained at debris and a sort of double vision or stretched image due to my strong astigmatism that was only partially corrected with corrective lenses. Oncoming cars looked like they had a second and third pair of headlights, one bold set at 1-2 o'clock (right eye) and a fainter set at 10-11 o'clock (left eye).
